So I have to replace a ground strap on my wife's car, which is a bare, braided copper wire that's tinned and solder blocked in the ends.
Because this particular ground strap is on the bottom of the engine to the bottom of the frame, it's especially exposed to the elements. It's right by the front tire on an AWD car, so it's bound to get full of junk. The previous one did, and rusted in half. Cool, huh?
My question is twofold:
- Why do we use these bare, braided straps instead of a shielded wire? Is it the flexibility?
- Can I solder-block the ends and shrink-tube the replacement to protect it?
